Radiator Filter For Automobile

ABSTRACT

A radiator filter for automobile includes a radiator, which includes a plurality of heat dissipation fins mounted on a surface of the radiator, wherein the radiator has a radiator water net and a radiator water outlet; and a filter, which is connected to the radiator water inlet of the radiator so that cooling water fed from an engine of the automobile is guided through the filter to remove impurity contained in the cooling water and the impurity-removed cooling water is fed through the radiator water inlet into the radiator for effecting heat exchange and thus achieving the purposes of cooling.

FIELD OF THE INVENTION

The present invention relates to a radiator filter for automobile, andin particular to a filter that filter off impurities entraining coolantbefore the coolant is fed from an engine of the automobile to a radiatoror that filters water of air heater water tank system before the wateris fed to the air heater water tank system.

BACKGROUND OF THE INVENTION

In the operation of an automobile engine, due to the explosion ofgasoline, a great amount of heat is generated, which leads to anincrease of surrounding temperature. Most of the power systems that areknown today use water as a coolant, which flows through a speciallydesigned water channel system to passes every components of the enginefor removal of heat therefrom. Depending on the arrangement used, thehigh temperature water will get to the apex of heat dissipation when itpasses through a radiator. The radiator is made of a metal of lowspecific heat, such as copper and alloy, to form a water collectionsystem, inside which tiny passages are formed to allow the liquid tocontact the surrounding low-temperature air when passing through thepassages to thereby dissipate heat. After passing the radiator, thetemperature of the liquid becomes lower than engine temperature and issubsequently returned to the engine to absorb and thus bring away heatto the radiator. Such a process is repeated.

However after long time of use or when the coolant fed to the radiatorcontains impurities, such as carbon-contained impurity or in case thatthe radiator has not been cleaned for a long time, such impurities mayget stuck among heat dissipation fins of the radiator, making the clapsbetween the heat dissipation fins shortened thereby making it no longerpossible for the heat dissipation fins to smoothly dissipate heat.Consequently, during the operation of the automobile, due to the heat ofthe radiator being not properly dissipated through the heat dissipationfins, the internal pressure of the radiator may get excessively high,leading to cracking of the radiator. The automobile may this get brokenduring the travel thereof and this may endanger the lives of the driverand the passengers.

SUMMARY OF THE INVENTION

An object of the present invention is to provide a radiator filter forautomobile, which is arranged between a water inlet of an automobileradiator and an engine to filter off impurities entraining coolant fedfrom the engine to the radiator so that no impurity may get stuck amongheat dissipation fins of the radiator when the coolant flows through theradiator thereby preventing the radiator from breaking due toexcessively high pressure inside the radiator caused by impurityaccumulated among the heat dissipation fins of the radiator and thuspreventing the automobile from getting broken during the travel thereof.

Another object of the present invention is to provide a radiator filterfor automobile, which can be easily installed in and removed from acooling system of an automobile and can be cleansed for repeated use.

A further object of the present invention is to provide a radiatorfilter for automobile, which can be used in an air heat water tanksystem for filtering water before the water is fed into the air heaterwater tank system to similarly remove impurity from the water to preventthe impurity entraining the water to cause any jamming making the airheater water tank system inoperable.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention discloses a radiator filter for automobile,wherein a filter is arranged in front of coolant fed from an engine to aradiator in order to remove impurity from the coolant and prevent theimpurity entraining the coolant from entering the radiator andaccumulating among heat dissipation fins of the radiator, consequentlymaking the radiator broken due to excessively high internal pressure. Tohelp fully understanding the present invention, a detailed descriptionis provided below to illustrate the process and the composition of thepresent invention. The manufacturing process and detailed steps of themanufacture of automobile radiators are not included in the descriptionof the details of the present invention in order to eliminateunnecessary constraint on the scope of the present invention. However,details of preferred embodiments of the present invention will beclearly presented. It is understood that besides such details, thepresent invention is also applicable to other embodiments and the scopeof the present invention is not limited thereto. The scope of thepresent invention is defined only by the appended claims.

Firstly, referring simultaneously to FIGS. 1 and 2. FIG. 1 is aschematic view showing a radiator the filter for automobile and FIG. 2is an exploded view of the radiator the filter for automobile shown inFIG. 1. Referring directly to FIG. 2, the radiator filter 10 comprisesat least a first cap 11, a first rubber sealing pad 12, a baffle 13, afilter net 14, a second rubber sealing pad 15, a transparent sleeve 16,and a second cap 17. The first cap 11 forms a filter water inlet 112 inan outside surface thereof and the second cap 17 forms a filter wateroutlet 172 in an outside surface thereof. The first rubber sealing pad12 is positioned on an inner side of the first cap 11. The baffle 13 isarranged at the inner end of the filter water inlet 112 of the first cap11. The baffle 13 comprises a block plate 132. The baffle 13 is fixedinside the first cap 11 by the block plate 132. Further, the filter net14 has a hollow structure 142 and thus, the baffle 13 is received in thehollow structure 142 of the filter net 14. The filter net 14 has aninside diameter that is greater than an outside diameter of the blockplate 132. When the baffle 13 is received in the hollow structure 142 ofthe filter net 14, the filter net 14 abuts and fixes the block plate 132of the baffle 13 in position, The transparent sleeve 16 of the radiatorfilter 10 has an inside diameter that is greater than an outsidediameter of the filter net 14 and thus the filter net 14 is receivablein the transparent sleeve 16. The transparent sleeve 16 is fit to aninner side (not shown) of the second cap 17 with the second rubbersealing pad 15 located between the second cap 17 and the transparentsleeve 16. Formed in an outside surface of the second cap 17 is a filterwater outlet 172.

In an embodiment of the present invention, the filter net 14 has a meshsize having a maximum opening diameter of 0.5 mm. The opening diameteris corresponding to spacing distance between heat dissipation fins 22 ofa radiator 20 (see FIG. 3) for the purposes of removing impurity oflarge size particles contained in cooling water with the filter net 14and preventing the cooling water that contains too many impurities fromentering the radiator 20 to cause the impurities accumulation among theheat dissipation fins 22 and thus leading to excessive pressure thatmight cause breaking of the radiator.

Further, in the present invention, the first rubber sealing pad 12 andthe second rubber seating pad 16 are provided for purposes of sealing,leaking prevention, and cushioning. The filter net 14 is made ofstainless steel or plastics.

Referring to FIG. 3, FIG. 3 is a cross-sectional view of the radiatorfilter for automobile. In FIG. 3, the radiator 20 comprises a pluralityof heat dissipation fins 22, a radiator water inlet 24, and a radiatorwater outlet 26. The plurality of heat dissipation fins 22 is arrangedon a surface of the radiator 20 to increase contact area of the radiator20 with air and thus increase heat dissipation efficiency. The radiatorwater inlet 24 is arranged at a top of the radiator 20 to receivecooling water (which is usually hot water) into the radiator 20. Theradiator water outlet 26 is arranged at a bottom of the radiator 20 toallow the cooling water flowing through the radiator 20 to be dischargedthrough the radiator water outlet 26.

Thus, in the present invention, the filter 10 is connected by a pipe 30to the radiator water inlet 24 of the radiator 20 and an opposite end of(not labeled) of the filter 10 is connected by another pipe 32 to anautomobile engine (not shown). Specifically, the filter 10 is connected,with the filter water outlet 172 of the second cap 17 shown in FIG. 2,to the radiator water inlet 24 of the radiator 20 by the pipe 30 and thefilter 10 is also connected, with the filter water inlet 112 of thefirst cap 11 shown in FIG. 2, to the automobile engine by another pipe32, whereby the filter 10 is arranged between the automobile engine andthe radiator 20, whereby before the cooling water is fed from the engineinto the radiator 10, the filter net 14 of the filter 10 first filtersoff the impurities entraining the cooling water so that the coolingwater fed into the radiator 20 contain no large size particle that mightget stuck among the heat dissipation fins 22 of the radiator 20.

In an embodiment of the present invention, the spacing distance betweenadjacent heat dissipation fins 22 of the radiator 20 is around 0.5 mm to1 mm and thus the mesh opening diameter of the filter net 14 of thefilter 10 is selected to be of a maximum value of 0.5 mm. When thecooling water flows from the automobile engine through the filter 10,large size particles entraining the cooling water are intercepted by thefilter net 14 and are not allowed further entraining the water flow intothe radiator 20. This ensures that the cooling water flowing through theradiator 20 does not carry large size particles and no accumulation ofimpurity among the heat dissipation fins 22 will occur. Thus, thepotential risk that the radiator 20 is broken by excessive pressure isalleviated. Further, the transparent sleeve 16 of the filter 10disclosed in the present invention can be used for visual inspection ofaccumulation of impurity to determine if it is necessary to remove thefilter for cleansing. The filter so cleansed can be used again. Theinstallation and removal of the filter are easy, making it easilyapplicable to automobile cooling system and an air heater water tanksystem and the time and expense that are needed for cleansing theradiator and water tank can be reduced.

Although the present invention has been described with reference to thepreferred embodiment thereof, it is apparent to those skilled in the artthat a variety of modifications and changes may be made withoutdeparting from the scope of the present invention which is intended tobe defined by the appended claims.
